The invention discloses a vehicle battery auxiliary cooling system and method and a vehicle. The system comprises a water cooling condenser, a cooling liquid inlet pipeline, a cooling liquid outlet pipeline, an expansion valve, a battery cooling heat exchanger and a compressor. Wherein the cooling liquid inlet pipeline and the cooling liquid outlet pipeline are respectively connected with the water cooling condenser and form an external liquid cooling loop; the water-cooling condenser, the expansion valve, the battery cooling heat exchanger and the compressor are sequentially connected to form a first internal refrigerating loop. Wherein the compressor compresses refrigerants and discharges high-temperature gaseous refrigerants, the high-temperature gaseous refrigerants are cooled through the water-cooling condenser and become liquid refrigerants, the liquid refrigerants are throttled into low-temperature refrigerants after flowing through the expansion valve, and the low-temperature refrigerants are subjected to evaporation heat exchange in the battery cooling heat exchanger. The battery cooling heat exchanger further cools the battery. Auxiliary cooling water is provided, effective control over the high pressure of a whole vehicle heat management loop refrigerant system is achieved, and the heat exchange effect is also improved.
